I use Photoshop CS4 now and I have a problem when I want to import (by dragging'n dropping, importing, open - I tried every way)a .png or i.e. also an .jpg:

when I worked a short time with PS (i.e. 10 minutes) and want to open a .png then, there comes the popup-window with:
"Could not complete your request because the file-format module cannot parse the file"

The funny thing is: my file is NOT broken!! Because if I then shutdown PS and open it again, there is no longer a problem to open the .png-file.... after a while of course it comes back...

So all solutions that I found on this problem were "the norton anti virus is also running"-solution: but I have no NAV running!!
And the files are NOT damaged!! Otherwise I couldn't have opened it after restarting PS.

I purged all files and I have enough cache!! So it doesn't seem to be a problem of my computerperformance.

Can you tell us a little more about your setup? If the problem went away when you eliminated your preferences, then returned -- The question is why are your preferences getting borked in the first place. Something unusual is happening.

well - I don't think that it was kind of fixed when I eliminated my preferences, and then came back... I think it wasn't even fixed! Sometimes this problem occured after 10 minutes - sometimes it went good for 1 day!

To explain my workflow:
I open PS and my last work: a psd. Of course my psd has sometimes many layers (about 50) sometimes less. Maybe I open another psd... with this two files open, I work and sometimes save.
Then I want to open an png in PS. AND: the problem occures!

Sometimes I even had no psd-file open! I just opened a few png-files in PS, but when I want to open the 7th or 8th png: Problem again!

I have no other "heavy programs" running: maybe outlook, skype and one Firefox-Window with two or three tabs.

OK so do you have enough scratch disk and ram assigned to Photoshop to be working with so many image levels/images at the same time ? I don't recall you posting your system specs. I'm leaning toward a memory issue; corrupting your preferences (assuming that you don't have enough memory space to be working with that many files open continuously). Of course can't rule this out until seeing the specs.

SDA - if RAM or scratch space were low, nina would get an error message saying so.

But the error message reported means that the file is corrupt (can't be parsed).

But if the same file works sometimes and not others - that indicates some other problem. Possibilities are: bad RAM, interference from another app (virus, anti-virus, disk utility, etc.), bad hard disk system, a seriously malfunctioning third party plugin (especially if you are using a third party PNG plugin), etc.

Meanwhile I re-installed Photoshop and because of the missing positive result I then also re-installed my whole CS4-Package!!!

I don't get it! I never had this problem with CS3!! Since I installed CS4 this problem occures!!! *ARGH*

And I cannot understand why I should be zhe only one who has this problem!!! I really searched the whole internet - NO RESULTS!

If I want to batch some .png-files, i have no choce: I have to open them by hand and if after a while the problem shows up, I have to shut down PS and open it again and then the the manual opening goes on!

Any solutions?

Greetz,

Nina

P.S. My collegue has the same problem!!!!! And he heard it could be a bug.... well -- they didn't seem to have fixed it yet! argh!

-" Every time i open 2-3 "Big" document and i want to open a PNG i got the parsing error message."-

I used to have this exact problem with CS3, but never 2ith CS4 or below CS3. (Win XP 32bit Quad Core CPU, Nvidia 9800, 4GB RAM)

However, i fixed it. My problem seemed to be the files location was in a deep directory and any png files i opened from there crashed photoshop. I simply moved the files and renamed aload of folders going down to the directory to make the path name shorter and it opened them fine. This solution worked, but i did see the probelm make a come-back after a few months that was not have been caused by the same thing.

exactly the same position as you were with exactly the same problem. I've tried everything mentioned

in the forums but to no avail. The one thing I didn't try was replacing the .8bi. file because that was for CS2 and CS3 and I don't know whether things are the same in CS4.

I can't believe how many people have this problem or why Adobe don't come out with a solution. - Unless I'm missing something of course.

I'm operating in Windows Vista Home Premium and CS4 Extended and have heaps of ram etc. I can open the PNG files in my old elements and CS3 so it's a problem with the software not the individual files.

fortunately I dont't have this problem anymore...but not, because I found a good solution.. but because I got a new computer and I think with little different hardware or preferences... I don't really know why, but since then I can work the same way I had worked before all this crab appeared.

I am sorry, that I cannot help you all with a better answer... I just hope, that this problem will never appear again...

But I cannot be sure.

Maybe this problem appears only when there are certain factors coming together .. and we all are one part of a "funky abnormal crowd".

My problem started after I did a factory reset on my laptop and reinstalled Design Premium. I can use all my Design Programs normally, except Ps. Isn't there anything that can be done to fix this? I didn't 'deactivate' Ps before I did the reset, could that be the problem? Don't know, it's a long shot, I'm sure.

My laptop will be replaced in a couple days...not because of this problem but because I'm upgrading. I would love to find a solution in case this happens again.

I have had the same problem like yours. So I just open the file in Paint Shop Pro X2, save it as a copy and open the copy in Photoshop. Then everything is fine. Some have done the same using GIMP. Maybe it won't work on the really botch corrupt files.

There are multiple files that this is happening to but the files are able to be opened in other applications including an earlier version of Photoshop. It doesn't matter if the file is opened from one hard drive or another as I have tried copying it to multiple HDDs to no avail. The file type is BMP and it opens just fine in Microsoft Picture and Paint. Brand new hard drive, memory diagnostics come back with no errors, clean OS install with Norton Internet Security 2010... if the problem is not Photoshop I will be very surprised. Especially considering I have not seen this in earlier versions and the amount of people reporting this issue would make it rather coincidental that we all happen to have the same environmental influences on file corruption.

Like you, I try to keep things in the "family," and that is why I use .PSD's, whenever I can. Now, when going to the Web, one obviously has to use other formats, like PNG. I recall when those were not supported on most browsers, and I had to use GIF, should the client need any form of Transparency. Luckily, those days are pretty much behind us. With Video, .PSD's work perfectly, and I can even Import_As_a_Sequence to keep my Layers, and then animate those to my heart's content. I am a big fan of .PSD's and seldom deviate from those, unless the client has specific needs, like TIFF, or JPEG, or PNG. I even resent when the Mac-based videographers insist on TGA's - "hey, just use PrPro and use .PSD's... "

C**p! Have just started getting this problem and googled it and came across this post. I am using mac osx 10.5.8 with creative suite4 and photoshop has just started with this problem. My problem relates to opening gif files. If anyone comes up with a working solution, please post. I just discovered I also have the same problem on my laptop (windows 7) which is brand new and did a quick test to see if it had the same problem there. Made a quick gif file, saved it and closed it and then tried to re-open it and voila same problem. I have written to adobe, so will keep this thread updated with their response. I referred them to this post. If anyone comes up with a working solution, please post. Thanks

Can I save my pngs as psd and retain all of the transparency properties?

Yes, .PSD's will save all Transparency, plus all Layers. Now, their use might depend on where the files will be used. With InDesign, AI, Premiere Pro (video), they will work perfectly. With some other applications, it's a big, "it depends."
